Cisco 2500 Family of Hub/Routers

Cisco 2505, Cisco 2507, Cisco 2516

The Cisco 2505, 2507, and 2516 are fully integrated hub/routers that enable remote offices to provide both LAN and internetwork connectivity. These hub/routers combine the functions of a stand alone hub and router in one chassis to provide simpler setup, improved serviceability and reliability, and integrated remote Simple Network Management Protocol (SNMP) network management.

Figure 1.: Two serial ports on the Cisco 2516 enable remote offices to support local SDLC devices, as well as high-speed access to core locations. The ISDN BRI port provides cost-effective connections to public or private networks using dial-up lines

In addition, through the BRI port, dial-up access is provided for backup or for low-cost, high-speed connectivity to private or public inter-networks. The two high-speed, synchronous serial WAN interfaces on each model deliver unprecedented flexibility, enabling access to leased lines, packet- and circuit-switched services, as well as -support of legacy systems such as IBM Synchronous Data Link Control (SDLC) devices.

All models use low-cost, unshielded twisted-pair cable wired in a star configuration for easy installation and offer from 8 (Cisco 2505), 14 (Cisco 2516), or 16 (Cisco 2507) Ethernet 10BaseT hub ports. No hub-to-router cabling is require. Everything is neatly contained in one compact desktop, rack-, or wall-mounted chassis.

Cisco 2516: ISDN Port Enables High-Speed, Low-Cost WAN Access

The Cisco 2516 includes an Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) port, allowing dial-up, high-speed access up to 128 kilobits per second (kbps).

Cisco 2516 allows easy expansion by enabling additional units to be daisy-chained together using one of the 10BaseT ports.

Central Network Management Eliminates Need for Remote Site Expertise

Cisco's hub/routers are easily managed from a central site using the CiscoWorks^™ graphical network management applications. Rather than managing a router and hub separately, CiscoWorks manages each hub/router with one consistent user interface. In addition, managers at central sites can:

• Configure hub ports using CiscoWorks. This suite of management applications automatically "learns" the model and hardware configuration of the device and provides a hub port configuration window.
  
  
• Graphically depict the router and hub physical configuration, including interface and port descriptions.
  
  
• Depict the status of interfaces and ports to easily identify -problems at a glance.
  
  
• Troubleshoot routine problems, including resetting a port or interface and gathering traffic statistics.
  
  

Cisco Internetwork Operating System Feature Sets

Cisco 2500 hub/routers can be ordered with any of seven Cisco Internetwork Operating Systems^™ (Cisco IOS) feature sets. They range from low-cost, IP-specific feature sets to Enterprise (EN) sets that contain the full Cisco IOS^™ protocol suite. Each set includes Cisco's unique AutoInstall capability, the "plug-and-play" router feature that allows rapid, economical router installation with -minimal expertise at remote sites.

Breadth of Software Functionality Delivers Cost Savings

Cisco 2500 hub/routers are available with a range of software -features that deliver significant savings on transmission costs. Dial-on-demand routing (DDR) facilitates use WAN links only when necessary. This reduces the cost of wide-area access and makes efficient use of ISDN or serial dial-up lines as alternatives to costly leased lines. The Cisco 2500 family of hub/routers also supports link compression for up to 128 kbps with Link Access Procedure, Balanced (LAPB) encapsulation, X.25 payload -compression, and Frame Relay header compression.

Dial backup provides a more economical solution than a second leased line when users require a backup link for disaster recovery. If access over the primary WAN link fails, the second dial-up line is automatically brought on line. This feature also supports the -activation of a second line for load-share traffic if the primary link becomes congested.
